Nursing Elites

1. A nurse is preparing to administer ampicillin 500 mg IV bolus every 6 hours. Available is ampicillin 500 mg in 50 mL dextrose 5% in water (D5W) to infuse over 20 minutes. The nurse should set the IV pump to deliver how many mL/hr?

• A. 100 mL/hr
• B. 150 mL/hr
• C. 200 mL/hr
• D. 250 mL/hr

Correct answer: B

Rationale: To infuse 50 mL over 20 minutes, the pump should be set to 150 mL/hr. This calculation ensures the correct rate for the infusion of the medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the given information.

2. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which of the following is a priority nursing intervention?

• A. Administer a dextrose 50% IV bolus
• B. Provide 8 oz of orange juice
• C. Administer regular insulin IV infusion
• D. Give oral metformin

Correct answer: C

Rationale: The correct answer is C: Administer regular insulin IV infusion. In diabetic ketoacidosis (DKA), the priority intervention is to rapidly decrease blood glucose levels. Administering regular insulin via IV infusion helps in lowering blood glucose effectively and quickly. Choice A, administering a dextrose 50% IV bolus, is incorrect because it would further increase blood sugar levels. Choice B, providing orange juice, is not appropriate for treating DKA as it contains sugar that will elevate blood glucose levels. Choice D, giving oral metformin, is not suitable for immediate blood glucose reduction as it acts over time and is not the first-line treatment for DKA.

3. A patient with a left arm fracture reports severe pain unrelieved by medication. What should the nurse assess for?

• A. Check for compartment syndrome
• B. Increase the pain medication
• C. Prepare the patient for surgery immediately
• D. Administer a sedative to calm the patient

Correct answer: A

Rationale: Correct answer: When a patient with a left arm fracture reports severe pain unrelieved by medication, the nurse should assess for compartment syndrome. Compartment syndrome is a condition where increased pressure within a muscle compartment compromises circulation and can lead to tissue damage. It is a surgical emergency that requires immediate intervention. Choice B is incorrect because simply increasing pain medication without identifying the cause of the unrelieved pain may mask symptoms of a serious issue like compartment syndrome. Choice C is incorrect as surgery would only be necessary if compartment syndrome is confirmed. Choice D is incorrect as administering a sedative does not address the underlying issue of unrelieved pain and may delay appropriate treatment.

4. An occupational health nurse in a factory is planning interventions to reduce environmental stressors for employees. Which of the following interventions should the nurse use to affect physical agents in the environment?

• A. Teach workers to choose personal strategies to cope with work stress
• B. Limit the amount of time workers spend in temperatures over 43.3°C (110°F)
• C. Provide ear plugs for use at workstations throughout the factory
• D. Obtain dosimeters for employees to wear when using new machinery that emits radiation

Correct answer: B

Rationale: Limiting exposure to extreme temperatures is important to protect workers from heat-related illnesses.

5. What are the main differences between a stroke caused by ischemia and one caused by hemorrhage?

• A. Blockage in a blood vessel supplying the brain
• B. Bleeding in the brain due to a ruptured aneurysm
• C. Administering thrombolytics if within the treatment window
• D. Avoiding anticoagulants and preparing for surgery

Correct answer: A

Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.
